This invention relatesto spring suspension means for motor-vehioles andparticularly to means for'supportin'g. thepivoted ended the springs.

In; constructions used in the past in which thesprings are providedwith' sh'aokles at one end andipivoted directly to the fra'me attheirother ends, each spring is pivoted. directly to a bolt carried by. theframe; 7, There are I many-objections to the use of this type of con:struction,- the principal obj eetionable featurebeing that-there is noprovision for;the 'ad justmentofthepartsto compensatelfor wear l of thesames: Another objection is thatthe friction surfaces have no meansior-satistacr torilylubrioating the same,hwhich results in a tendencyforthese parts to squeak and rattle; 1 V g It 'istherefore, the principalobject of this invention to provide a vehicle chassis with afnew andimproved; means for supporting the pivoted ends of thesprings. I

Another ob3ect; Is to 7 provide [a vehielechassis having ballbearingsfor supporting the pivotedlends oi the vehicle springs, with adjustingmeans forthe'bearings, and with;

- means forlocki'ngthe adj ustingmeans against rotation.
